Red metronome in black case with AY sticker

I lost my red digital metronome in a black soft case yesterday around 3pm. It’s about the size of a deck of cards, with a silver dial and a matte red shell, and there’s a small white sticker on the back with the initials 'AY'. I think I dropped it near the Peace Gardens by Pinstone Street, outside City Hall, after grabbing a coffee. This little metronome means a lot to me for piano practice and has sentimental value since it was a gift from my mentor; I’m really hoping to get it back. I can offer a small reward and am happy to meet somewhere in Sheffield city centre to collect it; I’m reachable here in the app.
